课时冲关23　Unit 5　Revealing nature Ⅰ.阅读理解A 体裁：说明文 话题：人造光对生态的影响 Rise with the sun and rest at sunset－this was the way of life for our ancestors. Thanks to artificial light, which improves visibility at night, we can enjoy a much safer society and around­the­clock productivity. For wildlife, however, studies have shown it disturbs animals' natural sleep cycles, affects amphibian(两栖的) reproduction and throws migrating birds off course. New research in Frontiers in Plant Science investigated how artificial light impacts plant­insect relationships. Researchers from Chinese Academy of Sciences noticed tree leaves in cities typically showed fewer signs of insect damage than those outside of cities, so they analyzed 5,500 leaf samples from two tree species throughout Beijing. Researchers found more artificial light in a given area meant tougher leaves. And the tougher the leaf, the less evidence of hungry insects. They don't fully understand why, but assume that trees under artificial light at night might be extending their photosynthesis(光合作用) time. “Plants distribute their limited resources, such as nutrients, water and energy, among various functions like growth, reproduction and defense, depending on the environment. Light can affect how plants use resources，” says Ellen Cieraad, a plant ecologist from New Zealand. “Since plants use light for growth, artificial night light could be unnaturally increasing the time trees spend on photosynthesis, allocating more resources to chemical compounds that make leaves tougher.” “If the same applied to leaves of other species, this would be bad news for insects，” researchers said. Changes in plants, and in interactions between plants and animals, can significantly impact the entire urban ecosystem. Herbivorous insects, which rely on leaves for food, may struggle to survive, disrupting the food chain. Fewer herbivorous insects could lead to declines in predators like birds, affecting biodiversity. Insects also play vital roles as pollinators(传粉媒介) and eat decaying plants, helping to break down leaves and returning nutrients to soil. In cities, healthy soil and healthy plant life supported by insects are good for humans, as plants provide shade and reduce heat trapped in cities. Moving forward, researchers are committed to refining their discovery, aiming to guide people to take corresponding actions. [语篇解读]　本文是一篇说明文。文章介绍了人造光对人类有益，但会干扰野生动物的自然睡眠周期，新研究还发现它会使树叶变硬，影响城市生态系统。 1．What influence does artificial light bring according to the text? A．It toughens tree leaves. B．It shortens animals' sleep hours. C．It illuminates birds' migrating routes. D．It increases amphibian reproduction rates. 解析：A　[细节理解题。根据第二段中“Researchers found more artificial light in a given area meant tougher leaves. (研究人员发现，特定区域的人造光越多，树叶就越坚硬。)”可知，人造光会使树叶变硬。] 2．Why is Ellen Cieraad quoted in Paragraph 3? A．To raise a concern. B．To introduce a concept. C．To support an assumption. D．To clarify a misunderstanding. 解析：C　[推理判断题。根据第二段中“They don't fully understand why, but assume that trees under artificial light at night might be extending their photosynthesis(光合作用) time. (他们并不完全明白原因，但推测夜间处于人造光下的树木可能会延长它们的光合作用时间。)”和第三段中引用Ellen Cieraad的话“Since plants use light for growth, artificial night light could be unnaturally increasing the time trees spend on photosynthesis, allocating more resources to chemical compounds that make leaves tougher. (由于植物利用光进行生长，夜间人造光可能会不自然地增加树木进行光合作用的时间，将更多的资源分配到使树叶更坚硬的化合物上。)”可推知，引用Ellen Cieraad的话是为了支持第二段中研究人员的假设。] 3．Which of the following best summarizes the phenomenon in Paragraph 4? A．Time heals all wounds. B．Nature always finds a way. C．A chain is as strong as its weakest link. D．A small move may affect the bigger picture. 解析：D　[主旨大意题。根据第四段中“Changes in plants, and in interactions between plants and animals, can significantly impact the entire urban ecosystem. Herbivorous insects, which rely on leaves for food, may struggle to survive, disrupting the food chain. Fewer herbivorous insects could lead to declines in predators like birds, affecting biodiversity. (植物的变化以及植物与动物之间相互作用的变化，会对整个城市生态系统产生重大影响。以树叶为食的食草昆虫可能难以生存，从而破坏食物链。食草昆虫数量的减少可能会导致鸟类等捕食者数量的减少，影响生物多样性。)”描述的现象可知，植物和动物间的小变化会影响整个城市生态系统，即小的变动可能会影响大局。故D项“A small move may affect the bigger picture.(一个小小的变动可能会影响大局。)”能概括该段现象。] 4．What will the following research probably focus on? A．Approaches to enhancing soil quality. B．Ways of improving urban biodiversity. C．Standards for selecting plant species in cities. D．Solutions to reducing impacts of nighttime light. 解析：D　[推理判断题。根据前文提到人造光对生态系统的诸多影响和最后一段中“Moving forward, researchers are committed to refining their discovery, aiming to guide people to take corresponding actions. (未来，研究人员致力于完善他们的发现，旨在引导人们采取相应的行动。)”可推断，后续研究可能会关注减少夜间人造光影响的解决方案。] 阅读理解B 体裁：记叙文 话题：生态学家和鸣角鸮的故事 It took an ill screech owl (鸣角鸮) to teach a scientist the value of upcloseandpersonal study. In his Harvad talk, Carl Safina, an ecologist and author of Alfie and Me: What Owls Know, What Humans Believe, recalled that the chick was found dying in his backyard. Safina took it in and planned to nurse it back to health and then perform release. But the owlet's flight feathers didn't grow properly. Safina delayed the release. Over those extended months, Safina got to know Alfie in ways that moved and changed him. “An owl found me and then I was watching ‘an owl’，” he said. “It was no longer an owl after a while, it was ‘she’ because she had a history with me. This little owl, who was with me much longer than I thought she would be, became an individual to me by that history and all those interactions.” The bond with Alfie strengthened to the point that, when she was finally released, she created a territory with Safina's home at its center. Safina was able to spend hours each day observing her in the woods as she learned to take care of herself in the wild, met two mates, and raised chicks of her own. When he heard Alfie calling, Safina said, he'd call back and she'd land nearby. Their closeness allowed him to learn more things about screech owls. Field guides, for example, describe two known calls but he identified six, some of which you have to be quite close to hear. The relationship also opened a window for Safina onto personality differences between Alfie and her mates. When pointed out that his approach to Alfie－including the act of naming her－ran counter to widespread scientific practice, Safina said he wasn't concerned about violating (违反) convention, particularly if something interesting like individual personality differences among owls could be learned. The experience caused Safina to think more deeply about humankind's relationship with nature and the kind of personal connection he was able to feel with a wild individual. “What I learned from Alfie is that all sentient (有情感的) beings seek a feeling of wellbeing and freedom of movement，” Safina said. “That's a guide to what's right and what's wrong to me.” [语篇解读]　本文是一篇记叙文。主要讲述了生态学家Carl Safina与一只名叫Alfie的鸣角鸮的故事，以及这段经历对他的影响。 5．What do we know about Alfie? A．She developed a close bond with Safina. B．She was a fictional character in Safina's book. C．She intentionally landed in Safina's backyard. D．She was dying because of the broken flight feathers. 解析：A　[细节理解题。根据文章第二段“Over those extended months, Safina got to know Alfie in ways that moved and changed him.(在那些漫长的月份里，萨菲纳以一种感动并改变他的方式了解了阿尔菲。)”根据第三段“This little owl, who was with me much longer than I thought she would be, became an individual to me by that history and all those interactions.(这只小猫头鹰，它和我在一起的时间比我想象的要长得多，通过那段历史和所有这些互动，它成为了我的一部分。)”可知，Safina与Alfie建立了紧密的联系。] 6．What happened after Safina released Alfie? A．Alfie chose to stay with Safina at his home. B．They maintained a continous communication. C．Alfie met mates and raised chicks by herself. D．Safina kept his distance from her to prevent attachment. 解析：B　[细节理解题。根据文章第五段“When he heard Alfie calling, Safina said, he'd call back and she'd land nearby.(当他听到阿尔菲的叫声时，萨菲纳说，他会回应，她就会降落在附近。)”可知，他们保持了持续的交流。] 7．What did Safina achieve in his study? A．Recording six different calls of the screech owl. B．Identifying different types of owls by their calls. C．Learning how to release owls back into the wild. D．Understanding personality differences among owls. 解析：D　[细节理解题。根据文章第五段“The relationship also opened a window for Safina onto personality differences between Alfie and her mates.(这种关系也为萨菲纳打开了一个窗口，让他看到阿尔菲和她的伴侣之间的性格差异。)”可知，Safina理解了猫头鹰之间的性格差异。] 8．How did Safina's experience with Alfie impact him? A．He became more focused on exploring nature. B．He initiated his commitment to wildlife conservation. C．He developed a deep appreciation for the welfare of living creatures. D．He decided to guide readers to distinguish between right and wrong. 解析：C　[推理判断题。根据文章最后一段“‘What I learned from Alfie is that all sentient(有情感的) beings seek a feeling of wellbeing and freedom of movement，'Safina said. ‘That's a guide to what's right and what's wrong to me.’(‘我从阿尔菲那里学到的是，所有有情感的生物都寻求幸福感和自由的移动，’萨菲纳说。‘这对我来说是判断对错的指南。’)”可知，Safina对生物的幸福产生了深深的欣赏。] Ⅱ.阅读七选五 体裁：说明文 话题：与家人露营 Camping is a great way to spend family time. It provides great opportunities for kids to explore new places and try new activities. Even a campsite near home can open up a new world of excitement. __1__ If you are looking forward to your camping trip this summer, but are worried about keeping your parents entertained, here are a few easy suggestions. __2__ If you are camping in a mountainous area, try mountain biking. Encourage your parents to bring their bikes along on your camping trip. Flying along together through the bike trails near your campsite will be an exciting experience for you and your parents alike. Remember to bring along your helmet, so your parents don't have to worry about your safety and make sure they bring theirs as well. Go canoeing(独木舟)or fishing with your parents. Encourage your parents to rent a canoe. You can paddle(划) downstream if you are camping on a river, or you can move across the lake from one shore to another. If your parents like to fish and your camping trip is during the fishing season, bring along your fishing equipment. You can go out in the canoe in the early morning to experience the best fish. __3__ Bring along craft supplies. When you go camping with your family, bring along some basic craft supplies, like paper, glue and scissors. __4__ With these treasures you can create craft projects to remember your camping trip. If you are near the ocean you could collect shells with your parents and make a seashell mobile. Practice your nature identification. If you and your parents share an interest in nature, find a good insect, bird, plant, animal or tree identification book. __5__ Collect different species of leaves and try to identify them with your family. A．Take good security measures. B．Try a new outdoor sport together. C．Then later in the day you can cook your fish over the campfire. D．Autumn camping is becoming more popular with family campers. E．While exploring nature, pick up anything interesting you might find. F．Try to recognize the different species that you come across with your family. G．At times it is hard for you to share these new worlds with your family, though. [语篇解读]　这是一篇说明文。文章介绍了与家人露营时可以一起娱乐的几种做法。 1．G　[根据上文“Even a campsite near home can open up a new world of excitement.(即使是在家附近的露营地，也能开启一个新的令人兴奋的世界。)”及下文“ If you are looking forward to your camping trip this summer, but are worried about keeping your parents entertained, here are a few easy suggestions.(如果你期待这个夏天的露营旅行，但又担心不能让你的父母开心，这里有一些简单的建议。)”可知，设空处描述的为找到这样的露营地后，很难和家人进行快乐分享。选项G.“At times it is hard for you to share these new worlds with your family, though.(有时候，你很难和家人分享这些新世界。)”选项中share these new worlds与前文的a new world of excitement相呼应，符合语境。] 2．B　[结合设空处处于段首的位置可知，设空处为段落的主题句。根据下文“If you are camping in a mountainous area, try mountain biking.(如果你在山区露营，试试山地自行车。)”此处提到了在山区露营时，可以尝试山地自行车运动，讲了在野外露营的时候可以尝试新的户外运动。所以段首的主题句应该是和尝试新的方式露营有关。选项B.“Try a new outdoor sport together.(一起尝试一项新的户外运动。)”与下文内容一致。] 3．C　[根据上文“ If your parents like to fish and your camping trip is during the fishing season, bring along your fishing equipment. You can go out in the canoe in the early morning to experience the best fish.(如果你的父母喜欢钓鱼，而你的露营正好是在钓鱼季节，带上你的钓鱼装备。你可以在清晨乘独木舟出海，体验最好的钓鱼时刻。)”讲到可以在清晨乘独木舟出去钓鱼，选项C.“Then later in the day you can cook your fish over the campfire.(然后在一天的晚些时候，你可以在篝火上烤鱼。)”符合语境。] 4．E　[由本段的主题句“When you go camping with your family, bring along some basic craft supplies, like paper, glue and scissors.(当你和家人去野营的时候，带上一些基本的工艺用品，比如纸、胶水和剪刀。)”及下文“With these treasures you can create craft projects to remember your camping trip.(有了这些宝贝，你可以创作手工艺品，来纪念你的露营之旅。)”可知，设空处起承上启下的作用，选项E.“While exploring nature, pick up anything interesting you might find.(在探索大自然的时候，找到任何你可能发现的有趣的东西。)”符合语境。] 5．F　[根据上文“If you and your parents share an interest in nature, find a good insect, bird, plant, animal or tree identification book.(如果你和你的父母对大自然有共同的兴趣，找一本好的昆虫、鸟类、植物、动物或树木的识别书。)”可知，接下来可说明带上这样的书的作用。选项F.“Try to recognize the different species that you come across with your family.(尝试着认出你和你的家人遇到的不同物种。)”说明了这本书可以帮助认识不同物种，符合语境。] [日积月累]　阅读理解B This little owl, who was with me much longer than I thought she would be, became an individual to me by that history and all those interactions. 句中，主句主语是This_little_owl，谓语是became。 句意：这只小猫头鹰，它和我在一起的时间比我想象的要长得多，通过那段历史和所有这些互动，它成为了我的一部分。 学科网（北京）股份有限公司 $
